The present invention relates to an atomizer for liquids with which airis driven through a jet by means of a pump into which jet a pipe forliquid opens. The invention has as one of its principal objects theprovision of a container for liquid which is interchangeably arranged onthe atomizer and provided with means which automatically bring thecontainer in connection with the pipe line for the liquid on theatomizer and which closes said container automatically on its beingremoved from the atomizer.

Other objects will be apparent from the detailed description of severalembodiments of the present invention which will now be described by wayof example with reference to the accompanying drawing in order that theinvention be better understood and readily carried into effect.

Fig. 1 shows a first embodiment of the invention, showing the atomizerand liquid holding container in longitudinal section,

Fig. 2 shows on an enlarged scale a second embodiment of the inventionwith atomizer, partly in section, and

Fig. 3 a third embodiment of the invention with atomizer, partly insection.

According to the first embodiment of the invention shown in Fig. 1 a jetI is provided in the jet body 2. The jet duct is in connection with anair pump 3 consisting of a stationary hollow cylinder 4 and a piston 5arranged therein for longitudinal displacement, said piston beingprovided with a rubber seal 6. An air inlet pipe I is in connection withthe inside of the air pump 3, said inlet pipe at the same time servingas a guiding means for the piston 5 and as a piston rod. The free end ofthe air inlet pipe rests against a seal 911, secured to the operatinglever 9 which is under the action of a spring 8 contained within thepump. The operating lever 9 is arranged pivotally about a pin It! in ahousing, said housing having the shape of a handle and enclosing the airpump 3, between the jet body 2 and the air pump 3 being interposed aseal I2. A compression spring I3 forces the operating lever 9 into theposition of rest shown in the drawing, a stop M on the housing I Ilimiting the outward movement of the lever 9.

A conduit or pipe I5 for liquid opens into the jet I, said pipe beingformed of a short extension pointed or bevelled at its outer end tothereby facilitate projection of said tube into the interior of a bottleI6 serving as a container for liquid. The extension is of a lengthsufficient to permit dispensing of substantially the entire contents ofthe receptacle or bottle I6 under the action of the pump. The bottle islocated above the jet with its opening provided in the neck downwardlydirected (upside down position) so that the liquid contained therein canreach the jet I through the short tube piece I5 when the pump is beingoperated. On the neck of the bottle a closure sleeve I'I provided with alid is detachably secured by means of a screw connection, said sleevehaving a suitable opening in the lid to permit the entry of the pipe I5for the liquid. The bottle I6 is capable of being inserted in the'axialdirection with the cylindrical wall of the capsule ll into a suitableguiding means I8, said means being a cylindrical hollow body screwed onto the jet body 2. The elastic diaphragm I9 made e. g. of soft rubber isclamped between the edge of the neck of the bottle and the sleeve I! andserves on the one hand as a seal between the bottle I6 and the sleeve I1and on the other hand for closing the opening of the bottle on removalof the bottle from tubular piece I5. Behind the opening of the sleevelid the diaphragm I9 has a fine slot orifice which is formed by thepiercing action of the pointed end of pipe or tubular piece I5 when thebottle is fitted on to the atomizer for the first time and whichnormally closes under the action of the elasticity of the diaphragm I9.

On pressing on the outside of the operating lever 9 with the thumb ofthe hand gripping the handle the air present in the air pump is forcedthrough the jet I (forming dispensing and atomizing means) whereby asmall quantity of liquid is sucked from the bottle and is atomized inthe air stream. Due to the described arrangement of the bottle above thejet, the weight of the liquid assists the discharge of the liquid whenatomizing. During the extraction of the liquid a vaccum is formed in thecontainer which causes the corresponding volume of air to be suckedthrough the pipe line I5 immediately on cessation of the air flowthrough the jet in order to create an equalization of the pressure. Onreleasing the lever 9 it is rapidly moved back into its position of restby the action of the spring I3, whereby the seal 9a is lifted from theair inlet pipe I. The air flows through it into the pump and the pistoncan slide back again under the action of the spring 8. On renewedpressure on the operating lever 9 the seal 9a closes the air inlet pipe1, so that the air in the pump cylinder is forced to escape through thejet.

The combination atomizer and dispenser according to the inventionrequires neither an actual suction pipe nor a special air inlet orificein the container for liquid.

If the container l5 for the liquid is to be removed, be it because theatomizer is not being used or for the purpose of refilling the bottle orreplacing it by another one containing a different liquid, the containerI6 is simply withdrawn in the direction of the neck of the bottleupwardly out of the guiding means 18. In doing this the pipe line [5 forthe liquid slides out of the closable orifice of the diaphragm [9 whichorifice immediately closes due to the elasticity of said diaphragm, andthus the liquid is prevented from flowing out. The operation of fittinga bottle to the atomizer takes place in the most simple manner in theinverse sequence. The closing action of the orifice of the diaphragmholds the fitted bottle securely by pressure on the pipe line for theliquid in the guiding means it.

For refilling a bottle i6 which has become empty, said bottle is removedfrom the atomizer whereupon the sleeve i! can be unscrewed.

In Fig. 2 a somewhat simpler example of em bodirnent of the-atomizerpump is shown. Whilst the jet and the container for the liquid areexecuted similarly to the first example just described, the guidingmeans 58 serving as a carrier for said container constitutes a bore inthe jet'body 2. In this example the piston 5 of the air pump 3 isoperated by hand and by exertion of pressure by means or one finger, the

inlet of'the air suction pipe 1 being simultaneously closed by thefinger pressing on the piston. The airsu'ction' pipe 'I again servesaspiston rod which piston rod "is'slidably mounted in a passageway 2a ofthe jet-body'2. lThe air in the pump. cylinder 4'isforced throughalongitudinal recess la, arranged on the outside of the pipe 1" into thejet; and the air suction through the pipe 7 on releasing the piston 5similarly finds its way into the air pump through'this recess la;

The third embodiment shown in Fig. 3 distinguishes from the first twoexamples, in which the axis of motion of the piston of the pump lies inthe direction of discharge of thejet, by having a pipe line 26 bentat-right' angles between the jet landthe air pump 21, 22. Expedientlythe pipe line 20 is bent'in such a manner that the pump is operated by adownward pressure. The pump consists of a hollow cylinder 22 arrangedfor'axia-l displacement in the housing 2'! in which cylinder apumppistoninot shown) is fixedly arranged; The cylindrical body servingas guide means l8 for the insertion of the container l6 holding theliquid is formed of a single piece together with the jet body 2 in thisexample.

As the container for the liquid a bottle made of transparent materialmaybe employed, which bottle is provided with graduation markings forchecking the amount of liquid withdrawn. For the same purpose a markercapable of being axially displaced can be arranged around the bottlewhich marker is set before starting the atomizing to the height at whichthe level of the liquid is to be chosen upon the completion of theatomizing operation.
